Design files

Overview

The PMP10121 reference design uses the UCC28600 quasi-resonant flyback controller to generate 22V @ 3.5A from an AC input. This flyback converter is not isolated and no optocoupler is needed for regulation.

Features
  • Quasi-Resonant Flyback Topology
  • Four Point Average Efficiency  = 90.3% (Vin=230VAC)
  • 10% Load Efficiency = 89% (Vin=230VAC)
  • No Need For an Optocoupler
  • This reference design was built and tested and the test report is included
Output voltage options PMP10121.1
Vin (Min) (V) 165
Vin (Max) (V) 275
Vout (Nom) (V) 22
Iout (Max) (A) 3.5
Output Power (W) 77
Isolated/Non-Isolated Non-Isolated
